CHANNEL ACCESS TECHNIQUES FOR POSITIONING REFERENCE SIGNAL TRANSMISSION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17383745 titled 'CHANNEL ACCESS TECHNIQUES FOR POSITIONING REFERENCE SIGNAL TRANSMISSION
Simplified Explanation
Methods, systems, and devices for wireless communications are described in this patent application. The innovation involves a group of user equipment (UE) where a first UE performs a channel access procedure and transmits a positioning reference signal (PRS) to the second and third UEs over a sidelink communication link. The first UE transmits the PRS during a specific time interval of a transmission window. Upon receiving the first PRS, the second UE performs a channel access procedure and transmits a second PRS to the first UE during a different time interval of the transmission window. The second PRS is multiplexed with a third PRS transmitted by the third UE using frequency division multiplexing (FDM) or code division multiplexing (CDM).
- A first user equipment (UE) performs a channel access procedure and transmits a positioning reference signal (PRS) to other UEs in a group over a sidelink communication link.
- The first UE transmits the PRS during a specific time interval of a transmission window.
- Upon receiving the first PRS, a second UE in the group performs a channel access procedure and transmits a second PRS to the first UE during a different time interval of the transmission window.
- The second PRS is multiplexed with a third PRS transmitted by a third UE in the group using frequency division multiplexing (FDM) or code division multiplexing (CDM).

- Improving the overall performance and reliability of wireless communications in a multi-UE environment.
Benefits
The benefits of this technology include:
- Enhanced positioning capabilities for user equipment in wireless networks.
- Improved coordination and synchronization among user equipment in a group setting.
- Efficient utilization of resources and increased reliability in wireless communications.
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may belong to a group of UEs that includes at least a second UE and a third UE. The first UE may perform a channel access procedure and, when the channel access procedure is successful, may transmit a first positioning reference signal (PRS) over a sidelink communication link to the second and third UEs. The first UE may transmit the first PRS during a first time interval of a transmission window. Based on receiving the first PRS, the second UE may perform a channel access procedure and may transmit a second PRS to the first UE during a second time interval of the transmission window. The second PRS may be multiplexed (e.g., using frequency division multiplexing (FDM) or code division multiplexing (CDM)) with at least a third PRS transmitted by the third UE.
